I find that Chinese often find difficulty pronouncing the end of some English words, e.g. 'Fault' pronounced as 'fau'.
I first noticed this with my Asian airline when some time ago, the Chinese Inflight Services Manager stormed into the cockpit, aggrieved about a just-messaged staff bonus that was less than expected. She shouted that she was not going to smile and wave at the pax as they disembarked, she was just going to tell them to 'fuh off'.
